Application filed May 1, 1915. Serial No. 25,331.

1 0 all whom it may concern:

Be it known that I, AARON N. WARFIELD, of the city of London, in the county of Middlesex, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Metal Cars, of which the fol-v lowing is'a specification.

This invention relates to cars in which the material employed in framing and sheet ing is practically entirely of metal, and my object is to produce a car which will possess the greatest possible strength proportionate to the weight of material employed, which will possess high powers of resistance to telescoping, which is conveniently arranged for the entrance and exit of passengers, in-

and

In the drawings like numerals of reference indicate corresponding parts in the dif ferent figures.

The basis of my construction is for the use of a web plate side girder at each side of the car. Each web plate side girder .1 is made of sufficiently stout material to provide ample vertical strength and is provided with the usual angular tension and com pression members at the bottom and top and is located in the middle of the side wall of the car. To the top member 38 'ofthese web plate side girders the posts 2 are suitably secured. These posts are preferably formed in one piece with the carlines 3 carrying the roof. The backbone of the floor construction is a box girder I which extends lengthwise of the floor nearly to the end of each platform as shown particularly in Fig. 3, stopping; however; before the extreme front of the vestibule is reached. To the sides of this box girder are suitably con nected the inner ends of the channel floor beams 5. The other ends of these are suitably connected to the sides of the web plate side girders close to their bottom members. Braces or truss straps 6 riveted to the flanges of the box girder are secured at each side to the channels 5 to secure the same in proper relationship to the box girder and brace them thereto.

' Braces or truss-straps 39 are also secured to the upper side of each channel and to the upper part of the bottom member 40 of each web plate side girder to brace said channels to the side girders. By using the channels in the floor construction and bracing them as described, I securea light floor framing well adapted to carry the load to the side girders which are expected to carry the loads.

Midway of each half of the car diagonal tension members 7 of L section are located secured at their ends to the web plate side girders.

Intermediate the channel floor beams 5 angle beams 8 are employed suitably secured to the sides of the box girders and to the sidegirders. In suitable positions toward each end of the car. are located the bolsters shown more particularly in Fig. 5. Each bolster comprises a pair of web members 9 secured to top and bottom plates 10 and 11. I To these plates the vertical web members 9 are secured by means of angles 12. Inside the web members 9 are stifiened by the channels 13 suitably riveted thereto. The plates 10 and 11 cross the box girder 4 as shown. The lower plate 11 carries the upper part of the bearing 1 f forming the connection between the bolster and the truck.

15 is the king bolt extending through the web plate side girders are extended inwardly toward the center line of the car providing transverse stiffness at these points. (See particularly Fig. The car platforms are located beyond these inwardly extended portions 16 of the side girders, bein supported by the ends of the central box girder of the floor. The end of the floor of the vestibule is supported on the frame 17 of angle bar construction suitably connected with the box girder. The vertical framing l8 and the outer end of the vestibule indicated in Fig. 8 is preferably of angle metal continued completely around from floor to floor through the roof.

Details of connections and other parts which are within the skill of the mechanic trained in the art are not particularly described.

While any seating plan may be employed, the arrangement shown in Fig. 2 with a central aisle and transverse seats for the most part a suitable one.

I prefer the arrangement of the doors as illustrated particularly in Fig. 2, a double central doorway being provided and a single door at each end. The platform of each doorway is sunk below the floor level of the car. The center platform is indicated by the numeral 19 and its outer end is sup ported by means of the framing 20 which connects the parts of the web plate side girder at opposite sides of the doorway and extends around the doorway.

The platform within the car supported on the members 21 of the floor framing. Two doors 22 swinging from the center of the door opening of the car side are preferably employed. The platforms 23 for the end doors are also dropped as shown, the outer edges of the platform being sup ported by the frame 2e extended around from the vestibule ends to the ends of the web plate side girders.

ith this construction no outside steps are needed the iassengers stepping up to the floor level of the car from the level of the doorway platform. Steps will of course preferably be provided within so that the level of the platforms of the doorways may be set at a convenient height above the ground level.

The roof construction has been partly described, the car lines being extended" completely across the roof. The ceiling will be sheeted in entirely save for ventilator openings as hereinafter described. Above the main roof is supported the monitor roof its framing being indicated by the numeral 25. The monitor roof is carried down at each end to the level of the main roof as indicated in Figs. 1 and 7.

Referring particularly to 4 and 7,

26 are the ventilator openings leading to the monitor roof which will usually be covered with suitable grillework. These openings communicate with the interior of the ventilator boxes 27 which are suitably secured in place and are opened at each end. These ends may be closed by the hinged doors 28. At each end of the monitor roof are located the side ventilator boxes 29 which communicate with openings in the sides of the monitor roof leading to the outer air and are open to the space within the roof at their ends facing toward the middle of the car in the direction of its length.

Shutters 30 are provided whereby the side ventilator boxes may be opened or closed. The doors 28 are connected by means of pivoted links 31 with a rod 32 slidable lengthwise of the car. Any suitable means may be provided for moving this rod to open or close the doors 28. The arrangement it will be seen is such that the doors at corresponding ends of each ventilator box 27 may be closed simultaneously and the others opened, and vice versa. The shutters 30 of the side ventilator boxes may also: be opened or closed by any suitable mechanism not shown.

Beneath the seats in the car floor or sides ventilator openings are provided for the admission of pure cool air from outside. The ordinary setting of the ventilator system is to have the doors 28, which are to the rear of the car when the latter is running, open, and also the rear side ventilator boxes. A suction is then created through the monitor roof which draws the foul air out of the car to be replaced by fresh air through the ventilator openings 83. The arrangement may be reversed if desired and fresh air allowed to enter through the forward side ventilator boxes 29 and through the forward ends of the ventilator boxes 28, thence through the openings beneath the said boxes into the car. It will be understood of course that any means may be provided for operating the controlling doors.

The window and door frames are preferably constructed as shown more particularly in Figs. 9 and 10. The stiles and rails are formed of hollow sheet metal members 34 which are incased in hollow outer members 35 in which are formed the grooves 36 for the glass.

Except where it may be necessary to leave a rail or stile removable for introducing the glass. the members 35 and 36 may be welded together at the joints. Where a rail or stile is to be made removable the outer members are mitered together as shown and through screws are employed passing through the holes 37 to hold the parts together. An all metal door or window frame is thus provided.

The bearing 14: hereinbefore referred to is of special construction. The upper part is formed with an annular projection 41 which is adapted to fit into a similar shaped recess formed in the lower member of the hearing. A suitable sort of washer 42 is preferably fitted in the bottom of the recess as shown to hold lubricant. At each side of the projection 41 in the upper member of the bearing is formed a small annular recess 43. A similar cooperating annular recess is formed in the lower member of the bearing, and into these recesses are fitted the dust washers 44: preferably of felt, rubber or similar flexible material. These washers efiectually exclude dust from the inner bearing surfaces.

Within the upper member of the bearing are formed a plurality of oil chambers 45 communicating by means of the ducts 46 with the bearing surfaces of the bearing. Oil supply ducts 47 lead from these chambers 45 through the upper surface of the bearing. Communicating holes 4:8 are formed through the bolster communicating with the ducts 47 through which oil may be introduced into the chambers.

The sheeting of the floor, sides and roof of the car may be according to any desired plan forming no particular part of the present invention which relates more particularly to the features of the framing and construction hereinbefore referred to. The construction of the main framing of the car is of the greatest importance. By the arrangement of the side girders as shown I obtain great strength in the sides of the car with great resistance to telescoping.

Both the dead weight and the live weight in my car are carried by the side girders supplemented of course to some extent by the box girder in the floor.

The construction provided is simple and easily constructed possessing many advantages over the hollow side construction commonly employed in which the side posts extend down to the floor level.

What I claim as my invention is:

1. In a metal car, the combination with web plate side girders each having uninterrupted walls provided with a top compression member and a bottom tension member; floor beams secured to the sides of said girders; and side posts having the lower ends thereof join the top compression members of the web side girders at points intermediate the floor and roof of the car.

2. In a metal car, the combination with central longitudinal box girders forming the backbone of a floor construction; web plate side girders having uninterrupted walls throughout the area thereof and each provided with a top compression member and a bottom tension member; floor beams connecting the sides of the box girder with the sides of the side girders adjacent the bottom tension member; plate girders extending transversely of the side plate girders toward the box girders; and side posts having the lower ends thereof joined the top compression members of the web side girders at points intermediate the floor and roof of a car.

Signed at Newark, Ohio, this 24th day of April, 1915, in the presence of the two undersigned witnesses.
